ATTORNEYS Patented Sept. 23, 1941 WINDOIIV SASH CONSTRUCTION Edward F. Chafiee, Syracuse, N. Y., assignor to The 0. M. Edwards Company, Inc., Syracuse, N. Y., a corporation of New York Application August 11, 1938, Serial No. 224,335

1 Claim.

This invention relates to window structures for buses, railway cars, and other structures in which the outer wall of the car or structure is composed of large sheets of metal, which are formed with window openings, and has for its object a sash structure secured to the sheeting and so formed that the margin of the sheeting around the window opening forms one wall f a groove for receiving a glazing strip which is readily removable or replaceable to permit the removal and replacing of the glass panel for any purpose, as for replacing broken glass or for washing inner faces of a double sash.

The construction results in a sash of minimum weight and thickness and one which is extremely economical in manufacture and readily installable and also one in which the outer surface of the glass pane is close to the plane of the outer surface of the sheeting, thus reducing air resistance.

The invention consists in the novel features and in the combinations and constructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanying drawing in which like characters designate corresponding parts in all the views.

Figure 1 is a fragmentary isometric view of the outer sheeting of a car body formed with a window opening. A

Figure 2 is an enlarged sectional view on line 2-2, Figure 1.

Figure 3 is a view smaller to Figure 2 of a double sash embodying this invention.

The invention comprises a sash opposed to the inner face of the sheeting of a car body or other structure and secured thereto with the margin of the wall around the window opening forming one side of a groove for receiving a glass retaining or glazing strip, the opposite wall of the groove being the outer side of the sash.

I designates the outer sheeting of a car body which is secured to the frame structure in any suitable manner, the sheeting being formed with window openings, as 2. 3 designates a metal sash frame formed in any suitable manner having a channel 4 for receiving the margin of a glass pane 5. The channel 4 is open at its outer side for permitting the glass 5 to be placed therein. The channel is here shown as right angular in cross-section and usually is provided with a lining B of rubber or other resilient material.

The sash is of skeleton form in cross-section and is provided with inner and outer flanges 1 and 8, the outer flange 8 is opposed to or confronts the margin 9 of the wall around the window opening and secured thereto, as by fastening members II]. Preferably, a heat insulating strip II is interposed between the flange 8 and the inner face of the sheeting I. The sash is formed on the side thereof opposed to the margin of the sheeting I with the inwardly facing channel I2 located to the outer side of the plane of the glass panel 5 and beyond the edge of the glass panel 5. This channel I2 is right angular in general form and is open at its outer side toward the margin 9,- so that the margin 9 forms the outer wall of the groove for receiving a glazing or retaining strip, the other walls of the groove being formed by the side and bottom of the channel l2.

I3 designates a glazing strip of resilient compressible material, as rubber, having a base flange I4 fitting the groove and a head portion so shaped as to be tensioned to press at I5 against the outer face of the glass when the base flange is placed in the groove, the head portion also having a lip I6 covering or pressing on the edge of the margin 9.

In operation, the sash is assembled in position relative to the window pening; the glass is then placed in position, and the glazing strip applied. The base flange of the glazing strip is preferably provided with lengthwise corrugations or barbs I1 for holding the glazing strip from displacement out of the groove, as the glazing strip of flexible material has a tendency to loop out of the groove.

By this structure, the sash can be made particularly light and of minimum transverse width, and the glass can be brought closer to the plane of the outer face of the sheeting, than in structures heretofore employed.

The sash on its inner side is assembled with the interior trim of the car in the usual manner.

In Figure 3 a double sash is shown in which the sash frame 30 is formed with two glass panes 50 with a space between them, the sash being also formed to receive an intermediate sealing and spacing strip 5|. The outer glazing strip I30 is the same as the glazing strip I3 (Figure 1). In the double sash, a similar glazing strip 53 is provided on the inner side of the sash but the groove 54 for receiving the base flange of the glazing strip 53 is formed completely in the sash structure.

What I claim is:

The combination with a car body including an outer sheeting formed with a window opening; of a sash arranged with its outer side confronting and secured to the inner face of the margin of thewall around the pening, a portion of the wall of the sash opposed to said margin being spaced from the margin to form with said margin a glazing strip channel, the sash being provided withmeans providing a recess angular in cross section for receiving the margin of a glass pane, the recess being open at its side toward the plane of said wall and having its bottom located in'a plane approximately flush with the edge of said wall, whereby the glass pane may be placed in the recess and removed therefrom through the Window opening, and a removable strip having a base portion fitted in said channel.
